acquisition of nationality. It may also be necessary to advocate and provide technical advice on changes to legislation and/or administrative practice. 71. Under the 1954 Convention, States Parties have an obligation to issue identity documents to stateless persons on their territory who do not possess a valid travel document. Where States do not do so and UNHCR has determined a person to be stateless, UNHCR Field Offices may issue a document to that effect which may help the individual in his or her dealings with authorities and are advised to contact the Division of International Protection for the appropriate format. 72. Regarding other protection concerns, notably detention and expulsion, UNHCR may need to intervene with the authorities as it does for refugees, asylum-seekers and returnees. Being stateless does not automatically entail a right to reside in a specific State. For more information, please refer to section IV.d. above. 73. UNHCR Field Offices are advised to register individual cases dealt with under UNHCR’s statelessness mandate in proGres. More detailed guidance will be issued on this in future. 74. For individual cases, which do not relate to the 1961 Convention, Field Offices must assess the resources that may be required to respond. They are advised to carefully prioritize in which cases they need to intervene and analyze how they go about responding. Relevant criteria for such prioritization and how individual cases are to be dealt with are, amongst others: • Gravity of issues faced; • Capacity at national level to provide such assistance; • Ability of UNHCR to achieve positive results; • Broader protection benefits to be achieved, for example as a basis for future good practice; • Legal framework; • Size of population and number of individuals requiring assistance; • Degree of social and economic integration. 75. Where a large number of persons who approach UNHCR or partners experience similar difficulties, it may be worth considering cooperating with a local or international NGO to which cases can be referred for advice and assistance.(48) UNHCR has established such information and legal advice programmes in a range of countries. Frequently such programmes are the only means of providing adequate support to individuals. VI. Setting priorities 76. Many UNHCR Field Offices experience constraints in staff and financial resources when planning statelessness activities. There is hence a need to set priorities. The Global Strategic Priorities provide critical guidance for such prioritization. UNHCR’s main priorities in the area of statelessness are the prevention and reduction of statelessness and the improvement of legal frameworks. Field Offices therefore need to prioritize: • Identification activities which are prerequisite for further action; • Measures which will help stateless persons/persons at risk of statelessness to acquire a nationality or to confirm their nationality (GSP 1.3); • The inclusion of safeguards in nationality legislation consistent with international standards, in particular the grant of nationality to children born in the territory who would otherwise be stateless (GSP 1.3); • Establishment of fair and efficient status determination procedures (GSP 2.2 and 2.3); • Improved access to birth registration (including late registration) by all persons of concern (GSP 2.5); 48 Executive Committee Conclusion No. 106 (LVII) – 2006, para.
